平原地区1000 kV交流特高压输电线路基础优化设计研究

Optimization Design of 1 000 kV UHVAC Transmission Line Foundation in Plain Area

针对1 000 k V榆横—潍坊交流输电线路工程铁塔基础作用力大、工程环境及地质条件复杂的实际情况,从基础选型及构造措施入手,进行基础优化设计。通过在基础设计中采用单桩基础、板式基础、群桩基础、钢筋布置、地脚螺栓偏心及基础圆形保护帽等各种优化措施,取得了良好的社会效益和经济效益。

In view of the actual situation of large force,engineering environment and geological conditions of the tower foundation of 1 000 k V AC transmission line project from Yuheng to Weifang,starting with the foundation selection and construction measures,the basic optimization design is carried out.According to the actual situation of force applied to foundation,the engineering environment and the geological conditions of 1 000 k V AC line project from Yuheng to Weifang,the basic optimization design is carried out from selection of foundation and structural measures to start.By adopting various optimization measures in foundation design including single pile foundation,plate foundation,pile group foundation,layout of reinforcement,eccentric connection of anchor bolts,circular protective cap of foundationetc,good social and economic benefits are achieved.
